PANY, OF INDIANAPOLIS, INDIANA, A OORPORATIONOF INDIANA. I

INVALID-BED,

Specification 'of Letters Patent.

Patented June 19, 1906.

- To all w/wmi it mag concern State ofIndiana, have invented a certain new and useful Invalids Bed, and we do hereby declare that the following is a full, clear, and

like numerals refer to like parts. I

The object of this invention is to provide an invalid s bed whereby the patient may be readily elevatedabove the mattress for any purpose without disturbing him or the bedclothing in the least andsupporting himin such elevated position for any desired length of time, changing the sheets, and easily lower nection with the be ing him upon the mattress. This object is attained by placing strong sheeting or can: vas on a mattress and securing it at its edges to aframe and then dproviding meansin constead for elevating said frame and holding the same in an elevated position, whereby. said sheeting and Tpatient are elevated above the mattress. his enables the patient to be served in any desired The full nature of the invention willbe understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a Perspective view of a bedstead with a mattress on it and said sheetin and frame, maintained in an elevated position. Fig. 2 is a plan vfewof thebedstead with the mattress and the sheeting-frame removed. Fig.3 is a longitudinal vertical section of the entire construction/as shown in Fig. 1, on the line 3 3 of Fig. 2.

.4. is aplan view of the actuating portion of the shaft. Fig. 5 is a central vertical section along one of the clamping cross-rods.

In detail the drawin s herein show an iron I bedstead of the usual orm and construction and having the side'rails 10, the end rails 11, the corner-posts 12, the posts at each end being connected integrally with the top. Upon said bedstead there is a wire mattress 13 and a cotton mattress-14, both ofthe usual char- 1 acter. The parts so far described may be made inlanydesired way. An iron frame 15 is provided that fits snugly between the ends 1 ofthe bedstead and is of about the same width as the frame of the wire mattress. At

head-rest is added to this construction consisti'ng of the iron frame 19, pivoted at to frame near the head of the bedstead. A head-rest 23, consisting of strong sheetingor canvas, is stretched on the frame 19. This sition of' elevation. In normalcondition the with the gear 27, and has secured to it a crank 29 for actuatin said toothed wheel 28 and gear-wheel 27 and shaft. Back action of said parts is prevented by the pawl 30, pivoted to one side rail of the bedstead in position to en age the gear 27 and so mounted and formed as to be actuated by gravity and yet be readily releasable. I

- Under each end of each side rail there is secured a guide-bar 32, so that the oppositelyplaced guide-bars will form pairs, one pair near the foot and one pair near the head. Within said guide-bars rods 33 are placed loosely, with both ends protruding somewhat beyond the'siderails of the bedstead. Upon said protruding ends the supporting-bars 34 are mounted. Said bars are pivoted their upper ends to the sides of the frame 15.

are threaded, .as shown in Fig. 5, to receive the clamping-nut 36, having a handle.

I Toeach rod 33 near each end under the bed and between the side rails a push-bar 38 rial, such as canvas, is secured stretched. A'

the sides of the frame 15 and supported by braces 21, that at the lower ends engage I notches in a toothed bar 22, secured to the head-rest may be adjusted to any desired posheeting 18 rests upon the mattress and the The rods 33 at one side of-the bedhaveheads on them and at the other side of the bed is pivoted. Clamping sleeves or tubes 37 are placed loosely on said rod 33 between the ifting-bars 34 at each end and the push-bars 38, and also betweensaid push-bars, so that there are three of said "clamping-tubes or three sections for each rod 33. Said pushbars at their other ends are looped around a gear-wheel 40, that is secured on the shaft, and onone sideof the loop there is a rack- 4.1. On each side of each gear 40 there is a collar 42 of larger diameter than the gear and wider than the loop, so as to hold the loop on the gear and I prevent -its lateral escape. Hence, as seenin Figs. Zand 3', the two loops on the two push-bars38 at each side of the bedstead extend. .in opposite directions, but ride upon and are. actuated by the same gearwheel 40. The rack- 41 is on the lower-side of One' loop and on the .upper side of. the other loop of each pair, so that the actuation of -.said shaft'25' in one direction willsimultaneously and equallymove the push-bars 38 rod's'33, and the lower ends of the supportingbars 34 toward the ends of; the bedstead.

'This -movementwill cause the elevation of the frame 1-5 and sheeting "18, asseen in Fig. 1.

" VVhen in such elevated position, the pawl will'-.lock the actuating parts; but to. make the supporting means effective the" clampnut 36 on each rod- 33 is turned, thus clamping the lower ends of the supporting-bars 34 tightly against the cl ampin -tubes 37 .-When the parts are thus clampe and locked, the

sheeting 18will be maintained in its elevated position under a considerable load. When it is desired to lower the patient, the crank '29lis held firmly, the pawl 30- disengaged, and then the frame 15' andsheeting Wlll lower under: the load by gravity, too rapid lowering being prevented by counter action of the hand on the crank 29. When the parts are lowered, they will be in the position shown Fig. 3.

-With this construction it-is observed that both ends of. the sheeting frame andsheeting will. be equally and simultaneously elevated and-lowered.

"ing-bar pivoted at the upperend tosaid frameat each side near'the end thereof, longitudinally extending guideways connected 5 5 with the side rails of said bedstead, rods extending under the bedstead and loosely through said guideways with the ends protruding and pivotally mounted in connection -with the lower ends of said supporting-bars,

and'means for moving said rods simultaneously toward the ends of the bedstead.

2. The combination with a bedstead, of a frame to which sheeting is secured, a slotted supporting-bar pivoted at the upper end to sald frame at each side near the end. thereof, longitudinally-eXtending guideways connected with the side rails of the bedstead, rods extending through the bedstead and loosely through saidguidewayswith theends 'protruding through the lower ends-of said supporting-bars, means for moving said "rods simultaneously toward the end of the bedstead, one-end of each of said rods being threaded, clamping-tubes on said rods and. a clamping-nut mountedon the threaded-end of eachrod for clamping the lower ends of said-supportingbars against the clampingtubes.

3. The combination with a bedstead, of a frameto which sheeting is secured, a supporting-bar pivoted at the upper end to said frame'ateach side near the end thereof, 1011- itudinall -extendin uidewavs connected with the side rails of the bedstead, rods extending under the bedstead and. loosely through said guideways with the ends protruding. and pivotal ly mounted in connection with the lower ends of said supporting-bars,

means for moving said rodssimultaneousl r toward the ends of the bedstead,-a shaft mounted under the bedstead about midway thereof transversely, means for actuating the same, a gear-wheel on each shaft near each end thereofyand a push-rod pivotally connected with each of said rods near each side of the bed that are. provided with loops at "their other ends surrounding the gears on saidshaft, each loop havinga rack for engaging the teeth of said gears on said shaft whereby said push-bars are moved horizontally in-opposite directions toward the ends of the bed by the actuation of said shaft.

In witness whereof we have hereunto 'afliXed our signatures in the presence of the witnesses herein named.
